Automobiles have, since their invention, revolutionized transportation, changing forever the way people travel, and do business. On the other hand, they have brought hazards, especially highway fatalities. However, today the application of computer technology and electronic sensors in designing and manufacturing cars makes it possible to eliminate most of traffic accidents. For example, electronic sensors mounted in your car can detect alcohol vapor in the air and refuse to start up the engine. They can also monitor road conditions by receiving radiosignals sent out from orbiting satellites and greatly reduce your chances of getting stuck in traffic jams.Text BComprehension Check2. a c c d b bTranslation5. 这类系统易受气候变化的影响，提供的数据不够精确，但他们不需要特别的`道路设施，只需要将车道标志维护好就行了。
